2 claims( e 01."` 2te-19) the like which are to be attached as a kind of liny ing to the edges of pieces of wearing apparel, such as uniforms for instance, or tothe edgesof seams f. and for other purposes in connection with the clothes making art, and it is intendedl to devise means of producing new and more durable kinds of articles of this description and to facilitate the method of manufacture thereof. In accordance with the previous art these peculiar kinds of 1i lining blanks were composed of a strip of cloth or other textile fabric of the desired color which was attached to the seam to be protected or lined vin this mannerY or inserted into such seam, by which means a kind of beaded edge was ob- Y'20 tained. With this arrangement the sometimes hollow or beaded round head is uniformly projecting from the two parts of fabric connected to each other and to which the strip, braid or strips being usually of a width of about 6 tenths,

of an'inch. There is the further inconvenience with this kind of lining blanks as heretofore manufactured that the protruding portion, after the piece of clothing or uniform has been worn for a comparatively short time only, was rubbed through and became of unsightly and untidy appearance.

In accordance with the improvement constituting thesubject of this invention a strip of textile fabric, preferably of cloth is provided for, one edge of which is shaped so as to comprise a solid enlargement of substantially round or circular cross-section and which is preferably and most conveniently produced by means of abandloom with suitably arranged warps and weft threads, the resulting product being then felted on special fulling machines so as to be converted into cloth, and being then colored in the usual manner.

Upon the Y' accompanying drawing we have shown by way of exemplication a fulling device which is particularly suitable for the treatment of the novel kind of lining blank, braid or the like referred to. AThe device is shown in Fig.

v9 which are passed over the stationarily supl infvertical cross sectionfg`- in Fig. 2 in' vertical longitudinal section.'- For'the vsake'rpfV illustra- Ation'yvel have alsoshown in Fig. Bethe lining'blanks referred 'toas heretofore manufactured; Fig'. `4bis e a cross'sectionalviewfof thenewb'lan'k, andFig. I 5 shows the sameinfp'ositionas sewn orptherfwise insert'edllbetween two pieces of ,textile fab- Fg. 6 illustrates thea'rran'gement"ofthe warp threads and weft threads in a band-loom.

As appears from Fig. 6 the warp threads 41 '65 are arranged in series in a'straight line while the .warp threads Y42 are disposed around an axisand are enveloped and retained by the fillers or weft threads in the usual manner. The warp threads 41 yield the at and the warp threads 42 the thickened or enlarged portion of the new lining blank which is obtained in endless strips and is Wound into yarns or hanks. Such hanks are fulled in the new fulling device accordingl to this invention, shown in Figs. 1 and 2, so that the article assumes a felted, cloth-like structure and appearance.

The new working device comprises a tank or other container `1 with `the fulling liquor 2 into which the hanks. 3 of the new lining blank which are passed over the lower roller 4 and upper roller 5 are immersed. The roller 4 is mounted upon two rockable levers 6 and is somewhat rotatable in its bearings 7. rv*The levers 6 are rocked on stationaryV pivots `8y and are suspended from cords ported guide rollers 10. The ends of the cords are provided with weightsll which compensate only a portion of the weight of the levers 6 and of the roller 7 tof a sufficient extent to cause the hanks to be suitably tensioned. One of the levers 6"may be detached from the roller 4, in order to allow of the hanks being passed over the roller 4. In case of the roller 5 being stationarily supported,'the hanksr may be applied by swinging the cover of the bearing 12 into the openposition and then lifting the studs 13 of the roller 4 fromA the bearings and swinging the roller 4 into the proper position. Upon the` same supports 14 e in which the roller 5 is mounted the rollers 15 rT100 and 16y are arranged which are forced against the roller 5 by the springs 17, 18 so that rthese rollers are displaceable in suitable guides with. relation to the periphery of the roller 5. This roller isdriven from a counter-shaft 22Aby means of a belt driving train 23, 24, 25, cooperating with the belt driving train 27, 28, 29 withvconical` adjusting collars or disks, so that the number. of revolutions of the shaft 26 may be changed 'e and acljusted.` The roller 1 5 hasno particular n110 y driving means, but it is frictionally driven by the friction produced by the hanks of lining blanks, braids and the like, and it may be arrested by a braking disk With brake band 31 and Weight 32.

The fulling action is due to the fact that the hanks of the lining blanks 3 Aafter having been circulated by the roller 5 in thedi-rection yof .the arrow are undergoing a resistance `on the roller 15 which produces a jolting action on vther-ihres, and a similar action is produced by the roller 16 which is operated with lower peripheral speed than theroller 5. As a result Kof this rubbing, jolting and hammering action, a condensation and felting is effected which imparts a cloth like structure and appearance to the strips of lining blanks. become shorter as a result of the jolting action, the rollers 4 and 5 will move towards each other in the course of the fulling operation, this move l ment on account of the compensating Weight 11 Abeine 'thout inuence uponthe operationof .the lullige device it ,should ,be understood ,that the invention is .not ,restricted to the particular temi@.ciinlerlt ,and

causing the band to travel in the manner of aV driving belt, and simultaneously producing pressure and friction on the band at a point in its travel.
